Just for peace of mind... Might be just over thinking... Read something about it long time ago but my search on the forum haven't been successful …
I'm using the 4ATTMIX to mix and add together trigger from TOPOGRAPH and TRIQ164 for my kick. I just wonder when they happen to be together if it's not dangerous for the trigger input of the modules (KICK or ENV modules)? Like if it guest over the 5v? Or is it buffered from the 4ATTMIX or else where? I didn't do it often but it's kind nice to be able to add the 4 on the floor with the TRIQ164 onto a groovy beat from the TOPPOGRAPH.
So all this to check if it's ok as it is adding trigger/gate on each other is fine or should I get a buffer/limiter to avoid getting over the 5v...

Don’t worry, that’s okay and actually a generally correct way to combine trigger signals. Another way would be by using OR logic (which is cheaper than a mixer, so more economical when you want to combine a lot of triggers).
What you don’t want to do is mix them with multiples.

To elaborate more broadly, in a system running on 5V (like AE), you cannot go over 5V in any way. If you want to do a mathematical 'addition' in electronics, like 2V + 2V => 4V, you need an active circuit that is powered, and you cannot exceed the voltage from the power rail (again, in AE that is a max of 5V). So for example, in AE, if you try to 'sum' a signal of 4V and 4V together (eg with a mixer), you will just get a signal clipped at 5V. That is your max voltage. Adding 3V and 3V together would also give 5V and so on. Clipping the mixer circuit (or another active circuit) like this is not a problem at all, it does not harm any component so its perfectly fine to do and even the wanted behaviour when you want to merge two triggers into one like here!
If you try to mix them passively, so like by plugging two triggers into a multipe, the outcome is unpredictable and depends on your triggers' output impedance. But on average, if your two trigger sources have the same output impedance, you'd end up with the mathematical 'mean' of the circuit. Eg. if you plug 0V and 4V in a multiple, you might get about 2V. In AE everything should be protected for doing this, but in other systems or with DIY stuff it can be dangerous (you can get large currents due to the unbuffered voltage differences).
Hope this makes sense! (and hope i didnt make any stupid mistake in my elaboration here)

What you don’t want to do is mix them with multiples. Even this is not harmful for the modules! But the OR Module would be the "official" choice for this. |

Thanks for the confirmations!
